This is the new Yanagisawa AWO1 model saxophone. While this is Yani's "entry" level horn, it is a true pro level instrument. The main difference between this horn and the AWO10 is a slight alteration to the neck octave design, and the lack of rib construction. This reduced weight on the AWO1 series makes it a slightly brighter, punchier horn. Also available is the AWO2 featuring a lacquered bronze tube.
